IMPROVEMENT IN FIRE-ESCAPE LADDERS.

Specification forming part of Letters Patent No. 124,541, dated March 12, 1872.

Speciiication describing a new and Improved Fire-Escape Ladder, invented by CARL GUS- TAV BUTTKEREIT, of Toledo, in the county of Tama and State of Iowa.

Figure l represents a face View of my improved re-escape ladder. Fig. 2 is an edge view of the same.

Similar letters of reference indicate corresponding parts.

These sections are made of wire or strap metal. Being connected in the manner shown, they can slide on one another, to be contracted into a small space, and a long ladder can be preserved in a box close to a window, whence it is thrown out through a window in case of re. The rounds ot' the ladder are the middle parts of the sections, as shown, and may be enlarged, if desired, by having plates or steps secured to them. The ends of each section, which are coiled around the upright parts of the next section below, may be extended out laterally, as at on a in Fig. 2, to form braces against the wall and keep the ladder a desired distance from the latter.

The ladder, if used as a fire-escape, can be suspended by a pin, b, from the inner side of the window, as shown. This pin may be readily drawn out, after the ladder has been used, by pulling on a cord, d, which is suspended from it. Then, by an extension rod, the ladder may be held up to another window to asl
